- The scaffolding protein Cnk binds to the receptor tyrosine kinase Alk to promote visceral founder cell specification in Drosophila
Alk signaling in the developing Drosophila visceral mesoderm requires the scaffolding protein Cnk and its binding partner Ave.
- TGF-β receptor I/II trafficking and signaling at primary cilia are inhibited by ceramide to attenuate cell migration and tumor metastasis
Ceramide forms complexes with Smad7 to inhibit cell migration–associated TGF-β–sonic hedgehog signaling in primary cilia.
- TCR-stimulated changes in cell surface CD46 expression generate type 1 regulatory T cells
Defects in the T cell receptor–stimulated processing of a cell surface receptor may contribute to the pathogenesis of autoimmune diseases.

About The Cover

Online Cover This week features a Research Article that identifies the scaffolding protein Cnk and its binding partner Ave as critical components downstream of the receptor tyrosine kinase Alk and its ligand Jeb in the developing Drosophila visceral mesoderm. The image shows the lack of visceral myotubes in embryos overexpressing Cnk (middle and bottom) compared to control embryos (top). [Image: Wolfstetter et al./Science Signaling]
